BLUETOOTH BASED SECURITY ENABLED POWERED DEVICES CONTROL

SYSTEM

The project mainly aims in designing completely automated powered devices

control with the help of Bluetooth technology and a graphical LCD to display the status

of the devices and also provides a user friendly environment to operate the devices

effectively. It majorly aims in providing a reliable system for illiterates and old people

who finds difficulty in operating few high end devices like AC, water heaters etc.

Automation is the most frequently spelled term in the field of electronics. The

hunger for automation brought many revolutions in the existing technologies. These had

greater importance than any other technologies due to its user-friendly nature. These can

be used as a replacement of the existing switches in home which produces sparks and

also results in fire accidents in few situations. Considering the advantages of Bluetooth an

advanced automation system was developed to control the devices.

The device consists of a microcontroller, which is interfaced with the input and

output modules, the controller acts as an intermediate medium between both of them. So

the controller can be termed as a control unit. The input module is nothing but a

Bluetooth module, which takes the input from the user’s mobile phone with Bluetooth

features and provides the same to the microcontroller. The output module is graphical

LCD and the devices to be controlled. Here the microcontroller receives the input from

the Bluetooth and switches the device with respect to the input. The controller also takes

the responsibility to display the status of the individual devices on the graphical LCD.

The Microcontroller is programmed using Embedded C language.
